Swansea have yet to fill the void created by the departure of Rodgers and some of the backroom staff from the Liberty Stadium.

Thomas believes that will help sway Sigurdsson's thinking.

"I think the player has to look at the future of Swansea City and look at who's going to be manager," said ex-winger Thomas, who also played for Wrexham and Chelsea.

"He does not know that yet. But Brendan Rodgers, who brought him to Swansea... gave him great confidence.

"And I can understand that when he has second thoughts about joining Swansea and maybe going to Liverpool, because Brendan Rodgers [is boss of] a far superior club and a far bigger club, he might want to go to Anfield."

Thomas also hopes Swansea's fans will be forgiving should Sigurdsson end up at Liverpool.

"I think they'll understand that if a bigger club comes in, a player will want to go - for ambitions, of course.

"And looking at Swansea's situation, they have no manager.

It's a very difficult decision that the player has to make, more than anyone.

"But the fans must understand he has to go somewhere better and there's no better place than Liverpool."
